Public bug reported:
Hi,
we had such cases in the past like bug 1817721 for bionic and maybe bug 1892130
is about the same as well. There were more but I didn't want to search for all
of them - what I checked is that there are no open ones clearly pointing out
the recent further drop in already flaky subtests.
In particular the tests "tests-in-lxd" and "systemd-fsckd" were known to
be flaky before, but got even worse.
Here stats of the last 40 runs, it might be a coincidences that this is
after 246-2ubuntu1 landed. Could as well be any other change

(I'm sure LP will make this unreadable, but is is nice in monospace)
Whatever the root cause is - the success rate of these has reduced so
much that the (even formerly questionable) practice of retry-until-
success won't work anymore.
I have run the two tests in a local VM and systemd-fsckd works there while
tests-in-lxd seems to trip over the old flaky fellow being "boot-and-services".
We had the discussion in the past, but I think I need to again bring up
the suggestion to skip "tests-in-lxd" and "systemd-fsckd" until they are
on reasonable success rates.
